Perhaps you should try some spelling variations:
nghe nam » nghe lam, nghiep nam, nghe nano
danh sai » danh bat, danh dau, hanh san
dung sai » dung tai, dung va, dung dat
va triet » va thiet, va trien, ve triet
te sach » toc sach
nang ma » tang ma, sang ma, nang cao
y nang » ky nang, ly nang, v nang
ma hoi » mai hoi, xa hoi, ma hoa
he nam » ha nam

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang ma hoi. hieu ((he nam) OR (nghe nam)) thu ha ((danh sai) or (dung sai)) va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ma hoi. hieu ((he nam) OR (nghe nam)) thu ha ((danh sai) OR (dung sai)) va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ma hoi. hieu ((he nam) OR (nghe nam)) thu ha ((danh sai) or (dung sai)) va triet".
• Adding a wildcard symbol may retrieve word variants: te sach y nang ma hoi. hieu ((he nam) OR (nghe nam)) thu ha ((danh sai) or (dung sai)) va triet*.
